Yeah, I have done some more playing around and this is what I have found... I found this article after looking up the effects of load and phase: http://www.sensorsmag.com/sensors/electric-magnetic/magnetic-sensors-and-timing-applications-935 The sensor can be represented by a voltage source the coil...

I'm sorry, but you're wrong about this, and it's easy to demonstrate why, while still obeying various laws of physics, some of which you seem to be ignoring. Simply apply a dead short (or something approximating it) to the output, and watch a near-zero voltage appear, no matter the speed it's going...

After reading on various forums about VR sensor input conditioning, all I could find was a lot of conflicting information and anecdotal reasoning for why certain circuits work. So I decided to do my own research from a hard facts and mathematical based standpoint. VR Sensors The VR Sensor has two im...

You are likely thinking of their evaluation board schematic, which uses two 5k in series instead of 1 10k. Can't remember the reason now, but it may have been to make the LPF more configurable. Just had a look, they are only there to share the current, so they can use lower wattage resistors. http:/...

Has there been much investigating into different values for the input capacitor? Looking at the data sheet for the NCV1124, there are a bunch of equations to calculate the input resistors and capacitors, for a given sensor impedance, peak voltage and frequency.

Yeah it was a vague quesion, sorry. The answer you have was exactly what I was after. If they were $100-$200 a connector that would be too expensive to justify making footprints. $10 -$50 is quite reasonable.

Whats the cost est. of these connectors? I will have a go at making one for my connector.

Hey Fred, Yeah I'm in Auckland, I saw some stuff about freeEMS on oldschool.co.nz a few years back, but only now am I financially and intellectually ready to play around with it. The AW11 is a fun car, but its a struggle to get through WOFs for some reason, mostly because of tinworm. The later 4AG(Z...

Ahh I see, ivan141's calculations assume the shunt is after the 10k resistors. he just rearranged P=(V^2)/R, and solved for V with a known P and R. Since with the shunt before the 10ks it no longer creates a voltage the divider, does the attenuation occur because of the pickup coils VA? By creating ...

Is there a quick and easy ignition system I grab off a car at pick a part?
